rad valve question

[86250rrider]

im using a 02b rad valve (86-98 cr250r) and it has the pro series reeds. are there any other choices for reeds in the rad valve other than this? wouldn't fiberglass give quicker revs than carb. fiber? :confused:

i choose to run the fiberglass reeds in mine. they last much longer than the carbon fiber. think the number is rl-19
